Abstract: A new and improved water and fertilizer dispensing apparatus includes a connector assembly for connecting to a source of pressurized water. A manually operated diverter valve assembly is connected to the water source connector assembly. The manually operated diverter valve assembly includes an input channel, a first output channel, a second output channel, and a selector valve assembly located between the input channel and both the first output channel and the second output channel. The selector valve assembly is used for manually selecting a water flow path from the input channel through either the first output channel, or the second output channel, or both the first output channel and the second output channel in combination. A mixing chamber is defined by a housing and is connected to the first output channel. The mixing chamber is used for containing a quantity of fertilizer (either solid or liquid) and a quantity of water for dissolving the fertilizer.
